Rodrigues, J.M. e Guedes Soares, C. (2017), “Ship vertical loads from using an adaptive mesh pressure integration technique for Froude-Krylov forces calculation”, Proceedings of the ASME 2016 36th International Conference on Ocean, Offshore and Arctic Engineering (OMAE17), 25-30 June, Trondheim, Norway
Dynamic vertical bending moments are determined for a military vessel hull in still water and under head waves, with a weakly nonlinear method. The domain for hydrostatic and undisturbed pressures integration is time-variant and generated with a quad-tree adaptive mesh algorithm, on which exact formulations for pressure on polygonal elements are used. Linear radiation and diffraction pressures, on another mesh superimposed with the aforementioned, are calculated with a frequency domain code. Results are compared with published experimental ones for small and large wave heights.
